PORTABLE DOOR- FASTENER;

SPECIFICATION forming part of' Letters Patent No. 290,352, datedDecember 18, 1883.

Application filed September 15 1883. (No model.)

I0 all whom it may concern.-

Be it known that I, EDWD. FRANKLIN PFUND, of Sacramento, in the countyof Sac ramento and State of California, have invented a new and usefulImprovement in Portable Door-Fasteners, of which the following is afull, clear, and exact description, reference being had to the annexeddrawings, forming part of this specification.

This invention relates to door fasteners which are adapted to be jammedin between the door and the casing and held by a part which is then setagainst the door; and the invention consists of the novel constructionhereinafter described and claimed.

In the drawings, Figure 1 is a plan view of the fastener, .showing partof the door and casing in section. Fig. 2 is a sectional view, showingthe fastener adjusted to hold a door where the latter does not fit thecasing closely; and Fig. 3 is a cross-section of Fig. 1.

The fastener is formed with a shank, A, having a spur, B, which isadapted to be inserted into the casing G in the usual manner. The outerend of the shank is enlarged and thread. ed, forming a squared screw, D,on which a sliding button or jaw, E, is arranged, the jaw having asquared opening to fit the squared screw, and this jaw is connected bymeans of a lip, 6, with a grooved thumb-nut, F, which screws on thescrew. By adjusting the nut and jaw toward the outer end of the screwand inserting the shank A between the casing G and the door G before thelatter is closed, the door may be shut on the shank, causing the spur Bto sink into the casing. The nut and jaw are then to be adjusted towardthe door until thejaw is forced against the same, as shown in Fig. 1.

In some cases the door or the casing has become sprung in some way sothat they no longer form the usual close joint when the door is closed.In such case the single shank and spur will not suffice to hold thedoor.

To adapt the fastener to be adjusted so that it will hold equally aswell in a large and a small crevice between the door and easing, I formthe screw D with a longitudinal groove, f, preferably a dovetail groove,and arrange in this groove, parallel with the main shank, .a slidingshank, H, having a spur, h, on its inner end, and a head, h, on itsouter end. The spur h, which is turned toward the door, is adapted tofill up any excess of space in the crevice to hold the spur B inengagement with the casing, as shown in Fig. 2. The jaw E is providedwith a recess, 9, to receive the spur h when the shank H is not to beused and is drawnback, as shown in Fig. 1. The spur It also serves as alip to prevent the shank H from being withdrawn from its seatinthescrew.

WVhat I claim is 1. lhe combination of the spurred shank A, having itsouter end provided with a squared screw, D, the grooved thumb-nut F,screwing on said screw, and the jaw E, having a squared opening andfitted loosely on the screw, and having a lip engaging with the groovein the thumb-nut, substantially as shown and described.

2. The combination, with the spurred shank and the adjustable jaw, of asupplemental shank arranged parallel with the main shank, and adapted tobe adjusted longitudinally, substantially as shown and described, andfor the purpose set forth.
